What Are the Reasons for Brake Noise?

Which Side is the Brake in an Automatic Transmission?

In automatic transmission models, the left side is the brake, and the right side is the accelerator. Precautions for automatic transmission cars are as follows: 1. The accelerator and brake in an automatic transmission car are relatively simple, with only two pedals located below the driver's seat and the console. From left to right, they are the brake pedal and the accelerator pedal, both controlled solely by the right foot. The gear shift is positioned in front of the center armrest on the right side, easily visible upon entering the car. 2. The main reason for this design is that the accelerator is used more frequently. Placing it on the outer side of the right foot provides a more comfortable posture for the driver. The brake is set on the inner side of the right foot, and the brake pedal is slightly higher than the accelerator pedal.

What does 5w40 mean?

The meaning of "5W-40" is as follows: 1. The "W" stands for "winter," indicating it is for winter use. The number 5 before the "W" represents the viscosity at low temperatures. The smaller the number, the better the fluidity at low temperatures and the stronger the cold resistance. 2. The "40" refers to the viscosity at 100°C. The larger the number, the higher the viscosity and the stronger the high-temperature resistance. 3. The "W" indicates the temperature range for oil usage, ranging from 0W, 5W, 10W, 15W, 20W, to 25W, etc. The smaller the number, the better the low-temperature fluidity, allowing it to perform better under low-temperature conditions. 4. The "40" indicates the viscosity of the oil at 100°C, with grades including SAE20, 30, 40, 50, and 60. The larger the number, the higher the viscosity. 5W50 is commonly referred to as multi-grade oil, meaning this oil meets the 5W viscosity requirement at low temperatures and the 40-grade viscosity requirement at 100°C.

What are the hazards of car lugging?

The hazards of car lugging include the following: 1. Low gear with high (speed) lugging; high gear with low (speed) lugging. Neither type of lugging is a good phenomenon, as both can cause damage to the machine and increase fuel consumption. 2. Severe wear on the clutch disc; 3. Significant wear and tear on the transmission; 4. According to the engine's load characteristics, when the throttle opening is small, the engine load rate is low, and fuel consumption is high. 5. If the vehicle frequently operates in a lugging state, the clutch, transmission, drive shaft, differential, and other transmission components may suffer from continuous impacts, leading to premature damage and a shortened lifespan. Additionally, the noise produced during lugging can be unbearable for passengers. 6. When driving in a lugging state, if an emergency situation arises requiring immediate acceleration to overcome an obstacle, pressing the accelerator may not result in an immediate speed increase, potentially leading to a passive situation.

How to Determine Transmission Abnormal Noise?

When the transmission inside the car makes a "rustling" sound during driving, it indicates abnormal noise from the transmission. Causes of transmission abnormal noise: 1. Long-term failure to replace transmission oil: Automatic transmission fluid should be replaced every 2 years or 40,000 kilometers, while manual transmission fluid requires replacement every 3 years or over 60,000 kilometers. Prolonged use of transmission oil leads to contamination with sludge and impurities, making it thicker and reducing fluidity, which intensifies friction between components and generates abnormal noise. 2. Presence of gear debris in the gears: When the abnormal noise is rhythmic, try increasing the throttle. In this case, the transmission needs inspection and timely repair or replacement of worn parts. 3. Use of poor-quality transmission oil: Inferior transmission oil has poor performance, is prone to oxidation, and forms sludge and residues that can clog filters and oil passages, increasing friction inside the transmission and causing abnormal noise.

What are the solutions for sluggish throttle response?

Solutions for sluggish throttle response are as follows: 1. Sluggish throttle response may be related to the gasoline octane rating. When refueling, always use the same octane rating and avoid frequent changes. 2. For slow throttle response, inspect components such as the intake valve, intake pipe, air filter, and hoses to check for blockages or damage. Address any issues promptly. 3. When checking the power transmission system, test-drive the vehicle to see if the transmission is slipping or experiencing gear engagement issues. 4. A faulty throttle pedal sensor can also cause sluggish throttle response. Professional repair is required in such cases. 5. It may be related to driving habits. Pressing the throttle too quickly or too slowly can lead to sluggish response. Maintain a balanced throttle input. 6. Insufficient fuel pressure or clogged fuel injectors can result in sluggish throttle response. In this case, cleaning the fuel system is necessary.

What does checking the VSC system mean?

VSC system stands for Vehicle Stability Control system. Here is the relevant introduction about the VSC system: 1. The VSC system can prevent oversteering or understeering during vehicle cornering, enabling the vehicle to quickly correct its path back to the original normal trajectory. The ABS (Anti-lock Braking System) ensures stability during emergency braking, the TRC (Traction Control System) controls the traction during vehicle start-up or rapid acceleration, while the VSC (Vehicle Stability Control) system maintains the stability of the vehicle during cornering. 2. During driving, the VSC system continuously monitors the driver's steering direction, vehicle speed, throttle opening, braking force, as well as the vehicle's tilt and roll rate through various sensors. It then determines the discrepancy between the vehicle's normal safe driving condition and the driver's intended operation. By adjusting the engine speed and the distribution of braking force on the wheels, it corrects oversteering or understeering. 3. The Vehicle Stability Control (VSC) system is an active safety system developed by Toyota, which significantly improves vehicle handling safety and driving convenience. In emergency situations such as sharp turns, rapid acceleration, or sudden braking, the system can quickly detect and take appropriate braking measures, such as controlling each tire individually while reducing engine output to maintain vehicle stability.
